The disclosed is a system and production processes, comprising a processor to perform the steps: a) obtaining a long-term production schedule containing production operations for a set of production orders by using forecasted values for production operation durations; b) deriving dispatching recommendations for suitable order release dates, dispatching sequences and/or resource choices of all subsequent operational dispatching decisions from the obtained long-term production schedule; c) obtaining a released subset of the set of production orders having each a release date and a due date and including information of all possible dispatching sequences and logical dependencies between them to produce a requested product; d) iteratively calculating subsequent operational dispatching decisions based on operational constraints and on the derived dispatching recommendations which support a decision-making in favor of optimizing the overall production process with respect to long-term objectives; e) outputting each calculated operational dispatching decision to a production executer.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system according to claim 1, wherein the at least one processor is configured to repeat steps c), d) and e) until the long-term production schedule has been adapted or re-calculated.
3. The system according to claim 1, wherein feedback from the production executer is returned for the iterative calculating according to d).
4. The system according to claim 1, wherein during calculating the limited number of subsequent operational dispatching decisions availability of required material and/or resources for performing the production operations is checked in real-time.
5. The system according to claim 1, wherein the relaxed at least one pre-determined production constraint relates to delivery by an autonomous guided vehicle.
6. The system according to claim 1, wherein each production process can include productive production operations and unproductive production operations.
7. The system according to the claim 1, wherein the calculated limited number of said operational dispatching decisions can be displayed on the output device in a Gantt chart.
9. The method according to claim 8, wherein steps c), d) and e) are repeated until the long-term production schedule has been adapted or re-calculated.
11. The computer program product according to claim 10, wherein the production processes further include a number of production operations for at least one assembly module, and wherein the method for providing short-term production schedule decisions includes controlling performance of the production operations by the at least one assembly module.
12. The system according to claim 1, wherein the production processes further include a number of production operations for at least one assembly module, and wherein the at least one processor is further configured to control performance of the production operations by the at least one assembly module.
13. The method according to claim 8, wherein the production processes further include a number of production operations for at least one assembly module, and wherein the method further comprises controlling performance of the production operations by the at least one assembly module.
14. The computer program product according to claim 11, wherein the at least one pre-determined production constraint is a storage constraint and/or material flow constraint.
15. The system according to claim 12, wherein the at least one pre-determined production constraint is a storage constraint and/or material flow constraint.
16. The method according to claim 13, wherein the at least one pre-determined production constraint is a storage constraint and/or material flow constraint.
